This DNA-based parentage test uses microsatellite marker analysis to compare the DNA profile of an offspring to the profiles of possible parents. The markers reported include the 12 ISAG-recommended markers for cattle. Genotypes follow the international nomenclature standard for cattle.
The Melanocortin 1 Receptor (MC1R) gene (also called Extension) controls the production of black and red pigments in the coats of domestic cattle, creating base colors that may then be further modified by other genes.
A freemartin is a female that is born as a twin with a male and is sterile as a result of exposure to masculinizing hormones produced by the male in utero.
Paunch calf syndrome (PCS) is an inherited lethal defect of Romagnola cattle characterized by abnormal development of multiple organs, craniofacial deformities, an enlarged fluid-filled abdomen, and liver fibrosis. Affected calves are usually stillborn.
Congenital pseudomyotonia (PMT) is a recessive genetic defect seen in Chianina and Romagnola cattle that impairs muscle function and is characterized by exercise-induced muscle cramping.
